Answer:
-3*3=-9
Step-by-step explanation:
So we see that the ratio between the two octagons is 7:1, since 28/4=7 so what we do next is multiply the values of the smaller octagon by 7. But that’s the long way. There’s actually a shortcut by multiplying the perimeter of the smaller octagon, 34, by 7. This in turn equals 238.
Answer:


Now, add these two equations.
You get,



Given,




You can test this to the other equation as well.


Hence, the two numbers are 14 and 10.
For two complex numbers

and

, the product is

That is, you multiply the moduli and add the arguments. You have

and

, so the product is
C is the correct answer for the problem hope it helps :)
